AUTOMATIC-DISCHARGE LUBRICATOR.

Specication of Letters Patent. Patented NOV. 15, 1910.

Application led September 24, 1908.

Serial No. 454,635.

that upon the opening of a valve the substance will be automatically discharged.

Said invention consists in 'a suitable receptacle divided into two chambers by means of a movable piston, one of the chambers being for the reception and storing of the substancein question, While the other is for the reception of a charge of air or equivalent compressible gas, each of said chambers being provided with a suitable valve.

While this appliance may be used for many purposes, l have especially designed it (in the fornrillustrated) as a lubricator; and one purpose for which such a lubricator. is especially well adapted is the lubrication ofthe Working part-s of motor vehicles, par ticularly when on the roadit being only necessary, as will be presently more fully explained, When lubrication of any such part is necessary, for the driver to bring the nozzle of the lubricator to the vicinity of suchpart, and cause the discharge valve to be opened, when the lubricant will be automatically discharged ont-o or into the part in question. i

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure l is a side elevation of a device of the character in question embodying my saidV invention; Fig. 2 a longitudinal sectional vieiv thereof on an enlarged scale the parts being adjusted ready for operation; Fig. 3 a detail sectional View on a still further enlarged scale similar' to a portion of Fig. 2 except that the parts are in the relative positions which they occupy when the discharge valve is open, and Fig. 4 a vieiv similar to Fig. 3 except that the parts are so adjusted as to hold the discharge valve tightly closed.`

In the form shoivnthe receptacle 21 is in the rform of a cylinder and contains a pishandle 28; and, at the other end, a head 29 to which the nozzle and valve are connected, and which embodies a valve seat for the discharge valve.

In the preferred form shovvn the discharge valve 31 has a tubular, exteriorly screwthreaded valve stem 32, through the side of which an opening is cut just below the head or valve proper. This valve rests on the valve'seat Within the cylinder head 29, and its stem 32 extends out through a suitable opening provided therefor leading outwardly from said valve seat. It is prevented from revolving by a stud 32 which passes in through the surrounding Wall and engages with a slot therein. Surrounding the valve stem, and also the tubular extension on the head 29 is an interiorly screw-threaded sleeve 33 engaging with the screw-threaded tubular stem of the Valve. This sleeve may be adjusted, as shown in Fig. 2, so that pressure thereon will move it and the valve stem backvvardly until the sleeve strikes a shoulder 29 on the head 29, as shown in Fig! 3, which will move the valve off its seat, and permit the lubricant (or other fluid or semifluid substance) contained Within the chamber f to flow out; or said sleeve may be screwed onto the valve stem until its end and the shoulder 29 come tightly together, as

shown in Fig. 4, in which conditionof the `parts the valve is tightly closed and locked.

For convenience I also apply a suitable nozzle to this device. Such a nozzle 35 is shown in Fig. l, and a fragment thereof in Figs. 2, 3 and 4. The form which I have selected for illustration is that of the nozzle of an ordinary oiler, and it is shown as having an to press the point of the nozzle against the part to be lubricated to push the nozzle and valve backwardly tothe position shown in Fig. 3, when the fluid or semi-fluid substance is free to be discharged through the opening in the side of the tubular valve-stein below lscribed will be readily the head or valve proper, and thence through ythe nozzle tothe part to which the substance is to be applied. At the opposite end of this structure, at or near the head 28, I'provide an ordinary check valve hLladapted to have a tube` or pipe leading from anI air compressor or other source from which air or gas under pressure may be. supplied connected thereto.' In preparing this apparatus for use, I first fill the chamber nearest the discharge valve with the fluid or semi-Huid substance,-generally by removing the head 9.9, and thus leavin@ the containing chamber open, thenreapplaying the head, and closing the valve.y I then, through the valve 4l, charge the air chamber with air or gas under suicient pressure so that when the discharge valve is opened the expansion of the compressed air or gas will be sufiicient to force the piston toward the discharge valveand thus discharge the contents of the containing chamber. When av sufiicient pressure of air or gas is obtained, the air com ressor is uncoupled, and the device is ready or use.

The great convenience of an appliance of this sort for such purposes as have been deunderstood. Many parts of a motor vehicle which need occasionally to be lubricated while in use are quite diiicult of ordinary access, and the advantages of an apparatus by means of which it is only necessary f to bring its discharge nozzle to the vicinity of such parts, whereupon, by a slight pressure, the lubricant is caused to be automatically discharged, are obvious. Many other uses for an apparatus embodying these features will readily suggest themselves; and, of course, the apparatus may be made of any size or shape to snit the particular requirements.

Having thus fully described mysaid invention, what I claim as new, and desire to secure by I/etters Patent, is

1. The combination of a container, and a discharge Valve thereto, said discharge valve ,having a tubular eXteriorly screw-threaded vvalve-stem with an opening thereinto below the valve head, and an nteriorly screwthreaded sleeve surrounding Aand engaging said valve-stein whereby the movement thereof maybe adjustably controlled.

The combination of a container, a discharge valve thereto, said discharge valve having a tubular exteriorly screw-threaded i valve-stein with an opening thereinto below the valve head, a stud engaging a groove in said valve-stein whereby it is prevented from turning, and an interiorly screwthreaded sleeve surrounding and engaging said valve-stem whereby the movement thereof may be adj ustably controlled.

In Witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana,

this twenty-second day of September, A. D. one thousand nine hundrediand eight.
